Calcined Alumina/Aluminium Oxide
Product name : Calcined Alumina/Aluminium Oxide
Item : JZBT-AO-2
Details :

Calcined Alumina 
Appearance: White powder
 
Material:
a -Al2O3 
Features: 
1. Stable crystal form
 
2. High hardness
 
3. Good resistance to abrasion
 
4. High mechanical strength
 
5. High melting point 6. Excellent electric insulating property
